MACHINE FOR USE IN THE MANUFACTURE 0F FOOTWEAR.

Application led December 26, 1913.

To all whom t may concern.'

Be it known tha-t I, HENRY J. Asnns, of Rochester, in the county ofMonroe and State of vNew York, have invented certain Improvements inMachines for Use in the `llianufacture of Footwear, which improveanents.are fully set forth in `the following specication and shown in theaccompanying drawings.

The present invention relates to the manufacture of footwear and to amachine used in such manufacture, and an object of the invention is toform the seats and toes of footwear of the type in which the upper isturned inwardly, so as to eliminate objectionable creases and obtain ashoe which is neater in appearance and has more symmetrical lines thanat present manufactured.

To these andl other ends the invention consists in certain parts andcombinations of parts all of which will be hereinafter described, thenovel featuresbeing pointed out in the appended claims. i In thedrawings; Figure l' is a top view of anillustrative machine embodyingthe present invention,- parts of the casing being shown in section so asto illustrate the mold# ing devices; Fig. 2 is a vertical section on theline a-c1, Fig. 1; Fig. 3 is a perspective View of one of the moldingmembers; Fig. 4 is a vertical section on the line i-J), Fig. 1, showingthe shoe out of engagement with the molding means; Fig. 5 isa viewsimilar to Fig. 1l. with parts broken awayto show the shoe 4engaging themolding means; Figs.

ture thereof. in eliminating the creases at .the toes and in properlyshaping the scat.

ary iron over which the vamp is moved back and forth while secured upona last. With this arrangement. only that portion above the edge of thesole or bend in the upper materials is smoothed out and this is done ina more or less defective way., depending Iiv the use of the illustratedembodiment of the present invention the upper materials on both sides ofthe sole edge line are smoothed out and the whole toe or the whole heelof the shoe after it has been lasted is molded l.simultaneously, and isalso preferably heated. the mold engaging not only the upper above thesole edge line or bend in the upper materials.

but also the bend at the sole edge line and a portion of the turned orunder-lapping stock ofthe upper so that a neat curve. ex-

, tending about the sole edge. is formed.

A machine which I have found desirable for carrying out the above methodcomprises a frame preferably formed of a horizontall 'extending portion-1 and an upright portion 2 at one end of the horizontall v extendingport-ion. Upon this upright portion may be arranged a holding meanscomprising preferably two molding members or Vdevices 3 which. whenassociated together,

are adapted to conform to the heel or to the toe of the footwear. Inthis instance. a machine is shown as designed forshaping the toe portionof the footwear, but it is ap parent that the machine may be readilychanged to shape alsol the .heel portion.

The nioldiug devices herein shown, which are more particularly adaptedfor the toe of a McKay shoe ora welt sh'oe afteri't has been lasted,each' have a curved wall i which at the niedian line of the shoe to apoint beyond the box of the shoe and above the bend gaging the bend or`sole edge line of'theiipper and a portion o substantially at 'rlghtfangles to the portion ,-l for engaging the 1nwardlvsturneil orunderlapplng stock. l:Any suitable means' may beemployed tor-supportingthese .moldingr devices so that theyv will have a `t'reedom of inovement.permitting them to conform to the shapefof the In this .instancia thesemolding de-v proximate ends olli' the dies or molds eachy have flatportions 1l abutting when the dies are not engaged b v the lshoe. andalso 'have portions 12 whichrserve as t'ulcrums on which the dies turnor rock relatively to each other for conforming to the end of Athe shoe,said portions 12 being at acute angles to the portions 11. From theabutting portions 11, the flange portions (S incline upwardly toward theouter ends of the molding devices at a slight angle to theplane ofmovement ot' the molding devices, so that thellanges may conform tothefplane of thefsole of the shoe when the latter is supported in ahorizontal position on a last; The vdies are normally held intheposition shown in Fig. 7 so that their )ortions 1l abut vieldinoineansbein l v e 'employed for this purpose. In thisinstance,

a yoked. men'iber- P13 has rollers 1l at the ends of'its two arms forengagement with the inner faces 1 5 of the two die members 3,

.said yoked member exerting pressure onthe proximate ends of the dies bymeans of a coiled spring lvmterposed between the. i1p.

right portion 2' of the casing and the yoked member.

In order lto guide the ldies 3 in a single plane of operation so thatthey will have no vertical movement, a zguiding.means is emy ployedcomprising preferably ktwo walls 17 and 18 arranged in parallel relationand forming a chamber between them, the yoke 13 also being guidedbetween said walls. The upper guide wall.17linay be a removable top wallfor the upright portion 2 of the frame of the machine and may berecessed or'cut away to the general curve of the dies or moldingdevices. .The depending front edge 'of the' cut away or recessed portionmay be engaged by the forward ends of the flanged portions G so astolimit they movelnentsof the molding devices under the action of thespring 16. The Tower guide wall 18 may beemployed for heating the diesor molding devices 3 to the desired temperature suitable for shrinkingor contracting the leather b v conduction. and to this vend anelectrical heating coil'19 is arranged ing coil between said wall 18 anda curved wall 21 bfa pocket 22 which is formed in the framed vportiony2Kbelovv. the molding dies in orderthat the'work on the work supportmaybe presentedtosuch dies.=

.i The work'fisupport l is preferably 'in they formof fallastilittedby'means'of its jack hole to faf in an inverted position, said stemvprefer bly/ A having screw-threaded engagement; .witlii lie-k carriage25 `in'xorder that, the lastl'nay belraisedvand loweredon' the carriageto locate'the plane of the toev bottom parallel [with the faces 6 of thedies 3. The carriage 21S-is preferably movable 1n horizontal ways'orguides 26 formedon the horizontalportionl of the frame'andl extending ina line parallel with themedian line through the molding devices inorder.` that the lastv may be moved toward and fromthe molding devices.l The means for moving this last or work support preferably embodies acam 27 arranged ona. horizontal shaft 2S located vertically below themolding devices and operable` through' the me-A Thlsshaft may also diumof4 a lever 29. y have a yoked member 30 guided thereon through thevmedium of slots 31, the yoke member straddling the can1127 which movesthe said yoke member inop osite directions on the shaft 28. In the yoejnylember 30, a

screw rod 32 is journaledto turn, said rod having its screw portion 33coperating with a slide or nut 34 which extends through a v slot the topof the frame portionlend is resiliently connected to the carriage25,1preff,

erably by means of a rod 35 surrounded by? a' snring 36 and adj ust-ablysecured to the carriage 25. justlnent in the operating means for accom'-modating the latter to lasts ofdite'rent lengths and is preferablyturned by a hand piece 3T arranged at one end'of the iii-ame portion 1.The elastic connection between the operating means and the carriage 25'is provided in order that the pressure of the The screw rod provides anad;

last Aagainst the molding devices may he resilient or yielding. It isapparent that the movement of the lever 29 moves the last toward andfrom the molding devices ina l horizontalvplane parallel with the planeof yielding or movement of the molding de-V vices, the last'beingaccommodated within the recessed portion 22 as it approaches and engagesthe molding devices.

lith the endvin vi'ewof supporting or pressing the bottom of the lastand the nppcrthereon against the surfaces and (3 ol the flanged portionsof the moiding devices, means is provided for exerting an upwardpressure against the toe portion of the last. In this instance, anengaging member 38 is employed which is preferably its covered with ayielding material or pad 39 n to-prevent injury to the upper on thelast.

This engaging device may be adjuetably ar-I ranged on a rod orvertically movable member l0 which near its upper' 'end is guidedthrough a collar 11, the latter in turn being resilientlv or vieldinglysupported for slight lateral movement and to this end carrying almrizontally extending stem :l2 guided in a perforated lug JfI-B andpressed in one direction b v a coil spring il which surrounds the stemand abuts at one end against the collar l1 and at the other end againstthe lug 43, This supporting rod 10 may also be op erated b v the cam 27,and, to this end, it carries at its lower end a yoke -i which straddlesthe shaft 2S to be guided vertically b v the latter and also straddlesthe cam 27 in order that the said caln may engage the yoke 45 to liftthe engaging device B8 after the said cam engages the yoke 3() to shiftthe last 23 toward the molding devices. A spring lil surrounds the rod40 between the voke l5 and the collar 11 and acts to depress theengaging device 38 and the rod 40 after the last has been moved awayfrom the molding devices. U

The operation of the mvcntlon w 1ll be understood from the foregoingdescriptlon but the contemplated manner of usmg the illustrative machinemay be summarized as follows: A lasted shoe while still on the last isplaced in an inverted position upon the adjustable support 21 so thatthe toe polnts toward the molding devices, the parts being adjusted, ofcourse, to the size of the shoe on which the machine 1s to operate. Byoperating the lever 29, the last and the shoe `are forced against themolding devices and particularly againstthe faces l thereof near theabutting ends of the molding devices. This causes the latter to rock ontheir pivots 8 which also shift to` permit the molding devices toconform to the shape of the toe. After a certain pressure has beenexerted upon the parts, the engaging member 38 moves upwardly to forcethe underlappingl stock of the upper against the face 6 and the face 5of the flange. The molding devices are preferably heated to asufficiently high degree to cause the leather to shrink and become` set,sothat, as the pressure is exerted simultaneously upon the whole end ofthe shoe, 1ncluding the turn or bend at the sole edge line and onopposite sides of the latter, the toe is molded into the shape of themolding devices which also conform to the shape of the last. Thistreatment of the shoe removes from'the -portions of the toe which willbe v exposed to view in the completed shoe the wrinkles, plaits, orcrimps which are occasioned by or formed in turnmg the upper inwardly atand adjacentv to the sole edgey line. The described mounting for themolding devices, by which they are conformable to the shoe, isapplicable to the end embracing plates or wipers used 1n lasting shoes,and the-shoe presenting means is adapted for use in lasting machines,and it vices, the same machine may be employed for molding the toes ofturn"` shoes. It is apparent also that the machine may be adapted formolding the heel portions of shoes, and such a heel portion moldingmachine has particular advantages when used with a turn shoe as it tendsto give a definite form to the heel counter, it being well known thatheel counters of turn" shoes cannot be molded before being inserted inthe shoes as is usually done in the manut'ac` ture of McKay shoes and inthe manufacture of many welt shoes. Y

The invention is illustrated as used in shaping the toe end of a McKayshoe after it has been lasted and while the upper material is secured inlasted position. In Fig. 8 is shown the condition of a lasted McKay shoeat'the toe end before treatment by the machine of the present invention,while Figs. 9 and 10 show the condition of the toe after being operatedupon by such machine. From these illustrations it will be seen that theend of the shoe is given the desired shape and that all crimps orwrinkles are eliminated` from the bend or sole edge line and also fromthose portions of the-upper upon opposite sides of the bend or sole edgeline. A further advantage from use of the invention on a McKay shoe isthat the shoe is in. a better condition to receive the outer sole, asthe latter may lie vflat against the underlapping stock of the upper inproximity to the sole edge line so that no space is provided between theshoe upper and the lower or outer sole.

The method of shaping or molding the ends of boots and shoes hereindisclosed is not claimed in this application, but is claimed indivisional application, Serial No. 19,693. filed April 7, 1915.
